A Worldwide Reputation for Excellence
Oriental Plaza, Beijing
In 1929 HALFEN started to produce adjustable connection systems in Germany which soon became known as “Halfen channels“. Now used worldwide, the amount of Halfen channels installed in the past 10 years alone would almost span the globe.
The product allows adjustable connections to precast concrete
as well as for concrete poured at the constructions site. Halfen
channels are ideal, for framing applications, and for facade fixing solutions. A highly competent Research and Development
team makes sure, that HALFEN-DEHA maintains its reputation
as technology leader by offering the most innovative and the
user-friendly fixing and anchoring systems.

WELDING
Welding is slow, is a fire risk, and needs to be closely checked for quality.
• Risk of sparks starting fires and damaging glass & aluminium
facade = high risk & high cost.
• Quality welding difficult to achieve and check on site =
high risk.
• Welding needs a lot of time and should be tested to verify
quality = slow installation & high risk.
• Painting required after welding to provide any corrosion
protection = poor corrosion protection, more time, another
operation to check, dripping paint damages facade and
creates health hazard.
• Heavy electrical equipment, trailing wires, and electricity =
safety hazards.
• Welds must be broken and re-welded if adjustment needed
after initial installation = slow installation.
• Embedded plates are designed per project and need testing
to verify performance.
Weld and paint splatter can cause expensive damage to the facade.
Welded connections require painting to give minimal corrosion protection.
18
Welding requires difficult repositioning of heavy equipment and a costly energy supply.
